Hyperbaric oxygen therapy in malignant otitis externa: a retrospective analysis.

PURPOSE: Malignant otitis externa (MOE) is a rare form of invasive osteomyelitis of the external ear canal. It is typically caused by Pseudomonas aeruginosa in immunocompromised patients. The diagnosis is clinical, and the initial treatment involves systemic antibiotics or antifungal therapy. Surgery is usually only considered when medical treatment has failed. Although hyperbaric oxygen therapy (HBOT) is recommended for refractory osteomyelitis, there are no specific guidelines for MOE. METHODS: This is a retrospective study that evaluates clinical data, treatment, and results obtained in patients diagnosed with MOE treated with HBOT at the Pedro Hispano Hospital between 2007 and 2022. RESULTS: During the study period, fifteen patients diagnosed with MOE were admitted for treatment with HBOT. All patients received antibiotic and/or antifungal therapy, and three required surgical intervention before starting HBOT. The pathology was successfully managed on all patients. CONCLUSIONS: HBOT may be an effective adjuvant treatment option in patients with MOE but it lacks robust scientific evidence. However, its therapeutic value should not be underestimated due to the good results and few adverse effects reported in recent retrospective studies and case reports.

Pharyngocutaneous Fistula Following Total Laryngectomy: a High-Volume Tertiary Centre Series.

Pharyngocutaneous fistula is the leading complication following total laryngectomy. It delays complementary treatments, speech rehabilitation and oral feeding. Despite evolving medical care, fistula incidence remains high. There is no consensus regarding risk factors for fistula development. A standard score for fistula prediction is lacking. Study population included all patients submitted to total laryngectomy (with or without pharyngectomy) due to laryngeal or hypopharyngeal tumours, occurring between January 1st, 2012, and December 31st, 2016. Patient demographics were recorded as well as disease and treatment variables. Statistical analysis was performed using the IBM SPSS Statistics 25®. A previously described predictive model for fistula occurrence was applied. A total of 212 patients were included, the vast majority with advanced local disease (97.5%). Only 10% were submitted to rescue surgery. Fistula incidence was 39.9%. Our rates of locally advanced tumours, with extensive hypopharyngeal involvement, were higher than in most series. Age, tumour location, diabetes, previous chemoradiotherapy, advanced local and regional disease, extensive pharyngectomy, flap reconstruction, manual suture and low post-operative albumin level were associated to fistula occurrence on univariate analysis. Only salvage surgery and advanced local disease remained significant on multivariate analysis. An adapted Cecatto score correlated with fistula occurrence but has not achieved statistical significance. Predictive models for fistula occurrence are lacking. Cecatto score showed promising results in our population but large multicentric studies are necessary for cut-off adjustments.

Risk Factors for Pharyngocutaneous Fistula Following Total Laryngectomy.

Pharyngocutaneous fistula is the leading complication following total laryngectomy. It delays complementary treatments, speech rehabilitation and oral feeding. Despite evolving medical care, fistula incidence remains high. There is no consensus regarding which patients are at higher risk for fistula development. This article comprised a literature review about risk factors for fistula development. All articles published on an on-line database (PUBMED™) using MESH terms "larynx cancer" and "fistula" in a 5-year period (January 1st, 2014 to January 27th, 2019) were included. Further articles were selected due to expert suggestion by one of the senior surgeons. Only articles written in Portuguese or English were included. Animal studies were excluded. 151 articles were selected and abstracts analysed. 82 articles were selected for full text revision. 32 were later excluded because they described single clinical cases, experimental surgical technics, irrelevant data or poor methodology. Final selection comprised 50 studies: 9 systematic reviews, one non-systematic review, 34 unicentric and 4 multicentric retrospective analysis and two prospective studies. There is no consensus regarding risk factors for fistula development. Patients submitted to salvage surgery for advanced disease seem to be at greater risk. Bad nutritional status is a logical contributor, but the ideal surrogate marker is still missing. Several variables are inconsistently pointed as risk factors and should be abandoned unless proved otherwise. There are no standard scores for fistula occurrence despite being a common complication following surgery.

Immune-Mediated Inner Ear Disease: Diagnostic and therapeutic approaches / Enfermedad inmunomediada del oído interno: diagnóstico y enfoques terapéuticos

Introduction: Immune Mediated Inner Ear Disease (IMIED) is a rare form of sensorineural bilateral hearing loss, usually progressing in weeks to months and responsive to immunosuppressive treatment. Despite recent advances, there is no consensus on diagnosis and optimal treatment. Methods: A review of articles on IMIED from the last 10 years was conducted using PubMed(R) database. Results: IMIED is a rare disease, mostly affecting middle aged women. It may be a primary ear disease or secondary to autoimmune systemic disease. A dual immune response (both cellular and humoral) seems to be involved. Cochlin may be the inner ear protein targeted in this disease. Distinction from other (core common) forms of neurosensory hearing loss is a challenge. Physical examination is mandatory for exclusion of other causes of hearing loss; audiometry identifies characteristic hearing curves. Laboratory and imaging studies are controversial since no diagnostic marker is available. Conclusion: Despite recent research, IMIED diagnosis remains exclusive. Steroids are the mainstay treatment; other therapies need further investigation. For refractory cases, cochlear implantation is an option and with good relative outcome

Introducción: La enfermedad inmunomediada del oído interno (EIMOI) es una forma rara de pérdida auditiva bilateral sensorineural, que progresa generalmente en semanas a meses y responde al tratamiento inmunosupresor. A pesar de los recientes avances, no hay consenso sobre el diagnóstico y el tratamiento óptimo. Métodos: Se realizó una revisión de artículos sobre la EAOI de los últimos 10 años utilizando la base de datos PubMed(R). Resultados: La EIMOI es una enfermedad rara que afecta principalmente a las mujeres de 2 a 50 años de edad. Puede ser una enfermedad del oído primaria o secundaria a una enfermedad sistémica autoinmune. Parece estar involucrada una respuesta inmune dual (tanto celular como humoral). La coclina parece ser la proteína del oído interno diana en esta enfermedad. La distinción de otras formas de pérdida de audición neurosensorial es un desafío. El examen físico es obligatorio para la exclusión de otras causas de pérdida de la audición; la audiometría identifica curvas características de pérdida de audición. Los estudios de laboratorio y de imágenes son controvertidos, ya que no hay marcador diagnóstico disponible. Conclusión: A pesar de la investigación reciente, el diagnóstico de la EAOI sigue siendo de exclusión. Los esteroides siguen siendo el pilar del tratamiento; otras terapéuticas necesitan más investigación. Para los casos refractarios, la implantación coclear es una opción con buen resultado relativo

Stridor as initial presentation of rolandic epilepsy.

The authors present the case of a 5-year-old girl referred to our institution due to several episodes of nocturnal stridor with ocular retroversion and parental notion of apnea. She has been previously submitted to adenotonsillectomy. Due to symptoms worsening she was referred to our hospital. Here, a nasal fiberoptic endoscopy evaluation was conducted and a diagnosis of laryngomalacia was done. The was submitted to CO2 laser ariepiglotoplasty with symptom improvement after surgery. During a follow-up appointment, parents reported self-limited clonic facial movements at sleep onset. The electroencephalogram (EEG) was compatible with benign childhood epileptiform discharges.

[Bockenheimer's syndrome. A clinical report]. / Síndrome de Bockenheimer. Caso clínico.

The authors report the clinical case of a 12-year-old boy with an extensive superficial venous network in almost every area of the body, present since birth and worsening in recent months, with the occurence of superficial venous thrombosis. No other changes on physical examination were noted, no symptoms and no analytical or imaging findings were found. Histological examination of the lesions revealed ectatic superficial veins without any proliferation of endothelial cells and the amount of elastin in the walls of these veins was decreased. The patient was diagnosed as a Bockenheimer's syndrome. The main features of this rare syndrome are described and discussed.
